AREVA e-terrahabitat is a core component of the Energy Management system that provides real-time data and process management services. e-terrahabitat contains vulnerabilities, including a buffer overflow. For more information on these issues AREVA customers should review the following issues in AREVA T&D Security Bulletin - ATD-08-002:

• PD28578 Buffer Overflow Vulnerability in e-terrahabitat MLF application
• PD32018 Denial of Service Vulnerability in e-terrahabitat WebFGServer application
• PD32020 Denial of Service Vulnerability in e-terrahabitat WebFGServer application
• PD32021 Denial of Service Vulnerability in e-terrahabitat NETIO application
• PD32022 Privilege Escalation in e-terrahabitat WebFGServer application

An unauthenticated attacker may be able to gain access with the privileges of the e-terrahabitat account or an administrator account and execute arbitrary commands, or cause a vulnerable system to crash.

Apply Patch
Users of e-terrahabitat version 5.5, 5.6, and 5.7 should apply the e-terrahabitat_560_P20081030_SEC patch immediately.

Upgrade

Users of affected software with versions 5.4 and earlier are encouraged to upgrade to 5.6 or above.

Intrusion Detection

According to AREVA T&D Security Bulletin - ATD-08-002:

Strong network perimeter access controls can reduce the potential avenues of attack. In cooperation with AREVA, the US Department of Homeland (DHS) Security Control Systems Security Program (CSSP) developed Snort based network intrusion detection signatures that are available for AREVA customer use only to detect attempts to exploit vulnerabilities within the WebFGServer. Due to unique system configuration dependencies, the signatures must be tuned to your specific environment. Please contact AREVA to obtain these signatures. DHS and AREVA cannot provide support for the signatures at this time.
Restrict Access

Limit network access to hosts that require connections to the portal. Do not allow access to the portal from untrusted networks such as the internet.
